• | TrawlEye Mode Depending on your operational needs or on the properties of your PX TrawlEye, you can choose how to see your echogram. If the PX TrawlEye is equipped with a Depth Lid and the depth measurement is enabled, you can also select to view the PX TrawlEye
echogram in true motion.
|
• | Sensor You can use two or more PX TrawlEye sensors simultaneously. If you have more than one PX TrawlEye sensors connected to your system, this is the place to select and identify the one you
want to see.
|
• | Range The Range parameter defines how “far” you want the TrawlEye to detect echoes. A better resolution is achieved using the shorter ranges.
|
• | Start Range If you do not want to see the echogram from 0 meters, you can establish an offset in the echogram in the Start Range function.
|
• | Horizontal Axis The echoes travel from right towards left across the echogram presentation.On the Horizontal Axis function you can choose the horizontal scale of the PX TrawlEye echogram. This controls the "speed" of the echoes.
|
• | Colour Scale The colour scales are designed to reflect how strong the echoes are. The echo strength is measured in decibels (dB). In the basic colour scale with 12 colours, each colour represents a 3 dB step. This means that the entire scale covers 36 dB. The dynamic range of the TV80 system is much larger. The Colour Scale parameters allow you to change the lower limit of colour scale range to match the current echoes.
|
• | Range Marker The Range Marker allows you to place a visual marker, which is a thick red horizontal line, to help you visualize and analyze the echoes on
the echogram view. The options available depend on the values you defined in the Range and Start Range functions.
|
• | Ping-Ping Filter The Ping-Ping Filter analyses the historical information from previous consecutive pings in order to remove unwanted noise and interference from
the echo presentation.
